File Sharing Help Needed on WinXP Home Network

If I want to share files/folders with 2 networks but the files/folders on each network is different to each other. Eg...
Network 1. Share folder 'abc' and all of its contents.
Network 2. Share folder 'xyz' and all of its contents.
To do that, I checked the share folder tab in properties of each folder to share it. Both folders are seen by both networks.

How do I show Network 1 the 'abc' folder and not 'xyz'?
And then... Network 2 the 'xyz' folder and not 'abc'?

I am using WinXP Home Ed and it is just a basic network of a PC and 2 laptops.

 

Enter a share name for your folder or drive and place a dollar sign ($) at the end of the name, i.e., MyPixx$ The name can be up to 12 characters long (including the dollar sign).
That's it!

That folder is now hidden and won't be visible by any other user on your network, nor will it appear in My Network Places or Network Neighborhood. Only by knowing the name of the folder can others access it, so make sure you choose a difficult name to guess if others trying to access it is an issue with you.

 

Cool foogoo. By doing this, I can let those that I want to allow access, say to 'xyz' folder. Rename it 'xyz$' then tell them the name of it and only they will see the folder.
